Oil type and maintenance notes
Choosing the right oil and keeping a regular change schedule helps protect the engine. For most climates, 5W-30 is the standard viscosity, and either conventional or synthetic-blend oils are suitable. Synthetic oil can allow longer intervals between changes, but you should always follow GM's guidelines and your local conditions. Use a quality filter and replace the oil drain gasket during a change.
Typical maintenance intervals vary by oil type and driving, but historical practice for this era suggests conventional oil changes every 3,000–5,000 miles and synthetic blends anywhere from 5,000–7,500 miles, depending on usage and oil brand. Always verify with the owner's manual or a trusted mechanic.
